NECK-YOKE.

SPECIFICATION forming part of Letters Patent No. 227,413, dated May 11, 1880.

Application filed October 24, 1879.

To all whom it muy concern Be it known that we, ALLEN B. CLARK and JOEL J. CLARK, of Canisteo, in the county ot' Steuben, State of New York, have invented a new and useful Improvement in Neck-Yokes, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.

Our invention relates to an improvement in neck-yokes; and it consists in an outer tube having two longitudinal slots cut through its side anda thimble to iit in each end of the tube, which thimbles are connected together by a spiral spring and provided with setserews, so that after one or both of the thimbles have been partially drawn out they can belocked in any desired position, as will be more fully described hereinafter.

Figure l is a perspective or" aneck-yoke embodying' our invention. Fig. 2 is a vertical longitudinal section of the same.

a represents the neck-yoke, which isformed from a metal tube and provided with a longitudinal slot, c, on each side of its center. Into the open ends of this hollow yoke are inserted the two eXtensible tubes d, which are closed at their outer ends and provided with the eyes e to receivek the rings g. The inner ends of these tubes d are open, so as Vto receive the ends of the spiral spring i, which is placed in between them. This spring serves to secure the two thimbles or tubes d together and to draw them back into the yoke after either one or both have been drawn out.

Passing throughthe slots into the thimbles are the set-screws o, which serve to lock the thimbles in any one place, and thus keep the yoke always ofthe same length. When these screws are left loose the thinibles play freely back and forth, and thus allow the horses to move outward to avoid mud-puddles, stones, or other obstructions that may be in the way.

Having thus described our invention, we claim- In a neck-yoke, the combination of a tube, at, provided with the two slots c, with the two thimbles d, spring i, and setscrews o, whereby the thimbles may either play freely in and out ofthe tube et, or the length of the yoke be kept always the same, substantially as shown.
